Large-Scale FDTD Computation for Computational Electromagnetics

Numerical Technology for Large-Scale Computational Electromagnetics

The key bottleneck of implicit computational electromagnetics tools for large complex geometries is the solution of the resulting linear system of equations. The goal of this effort was to research and develop critical numerical technology that alleviates this bottleneck for largescale computational electromagnetics (CEM). The mathematical operators and numerical formulations used in this arena...

Distributed Computational Electromagnetics Systems

We describe our development of a \real world" electromagnetic application on distributed computing systems. A computational electromagnetics (CEM) simulation for radar crosssection(RCS) modeling of full scale airborne systems has been ported to three networked workstation cluster systems: an IBM RS/6000 cluster with Ethernet connection; a DEC Alpha farm connected by a FDDI-based Gigaswitch; and...

Large-Scale Secure Computation

We are interested in secure computation protocols in settings where the number of parties is huge and their data even larger. Assuming the existence of a single-use broadcast channel (per player), we demonstrate statistically secure computation protocols for computing (multiple) arbitrary dynamic RAM programs over parties’ inputs, handling (1/3− ) fraction static corruptions, while preserving u...
